Conversion
Madame Guyon confided in a young monk how she had given herself to prayer, Bible reading, church attendance and charitable works, but had not found that spiritual joy she had once known. She even confided in him about the penances and general confession she had recently made. He told her, "Your efforts have been unsuccessful, Madame, because you have sought externally what you can only find within your soul. Accustom yourself to seek God in your heart, and you will not fail to find Him." He said she should be encouraged in her search for the reality of God, and advised her to seek her soul's salvation through simple faith in Jesus Christ, crucified and risen again, not by outward good works - as she had been attempting so vainly.
At twenty years old, she was truly born-again by the power of the living God. She was at peace with God! Cleansed from sin! Happy in the Lord!
What a dramatic change came to this once so active social butterfly! The change in her was unmistakably wrought by the operation of the Holy Spirit. Her understanding of spiritual things was enlightened. With no dreams, no visitation, nothing audible, that "still, small voice" spoke loudly to her soul, guiding her past the temptations of the world. To be wholly the Lord's wasn't easy in the hostile environment of the Guyon household.
Her marriage had never been based on mutual love, a kind of superficial affection passed between her husband and she merely as a marital duty acknowledged to the other.
Knowing that Madame Guyon always commemorated the date of her conversion, July 22, Sister Genevieve Granger wrote suggesting that she add to her act of consecration and commemorate this fourth anniversary of her conversion in a very special way - by signing a marriage covenant with the Savior. This was based on Revelation 19:7-8, "The marriage of the Lamb is come, and His wife hath made herself ready. And to her was granted that she should be arrayed in fine linen clean and white: for the fine linen is the righteousness of saints."
